The reason “As Time Goes By” is such a great song is that it celebrates the importance of the little things in life.

I say “little things” … actually they’re often “the big things”. For example, holding someone’s hand to show you love them is in many ways a little thing. It’s easy to do and almost inconsequential in terms of the effort it requires. But the love shown by that tiny gesture is, in fact, a big thing.

The Painting is ironic/comic by highlighting the ironies in the song which pokes fun at taking things too seriously
